摘要： A cleaning tool for a collection member cleans a collection member of a particle detector and includes a brush unit and a mount portion (52). The brush unit includes a bristle (54) and a woven portion (55) into which a root of the bristle (54) is woven so as to be held by the woven portion (55). The mount portion (52) includes a placement surface (52c) on which the woven portion (55) is placed and a securing portion to which the brush unit is bonded. In the cleaning tool for the collection member, the woven portion (55) includes two first outer surfaces (55a, 55b) that are located at respective ends of the placement surface (52c) and that extend parallel to a direction in which the bristle (54) extends. In the cleaning tool for the collection member, the brush unit (51) is secured to the mount portion (52) by bonding a region that includes at least part of each of the two first outer surfaces (55a, 55b) to the securing portion with an adhesive.

摘要： An object of the invention is to provide an optical element sealing structure that has good environmental resistance, and can be reduced in size. A sealing structure includes a lead frame (30) having a light transmitting section (38), an optical element (22) having an optical surface (41) which is directed to the light transmitting section (38) and is mounted on the lead frame (30) in such a state that the optical element blocks the light transmitting section (38) at its one end portion (48) in an axis direction, and a sealing body (29) that is formed in a region excluding an optical path (80) and seals the optical element (22). By forming the sealing body (29) in the region excluding the optical path (80), the light usage efficiency can be prevented from decreasing even when a material that can increase the environmental resistance is added to the sealing body. Further, since the optical element (22) is mounted on the lead frame (30) with its face down, the sealing structure (20) can be easily formed even when the optical element (22) is small-sized.
